[FIX] resource: 24h shift

Create a resource working 24 hours / day.
If we record it as:
- From 00:00 ; To 24:00 => crash
- From 00:00 ; To 23:59 => 1 minute lost

The `float_time` widget doesn't allow to be more accurate than 1 minute,
therefore it is not possible to record an end time of 23:59:59.999999.
We allow a value of 24:00 which is automatically interpreted as
23:59:59.999999. Only 1 microsecond is lost for such use case, which
should be acceptable for our level of accuracy.
